1. In its own words
The entity stated in its own words: its self-description, before any external description.
Shia Islam
Shia Islam began as the party of Ali and became a family of traditions ordered by the Imamate: the line of divinely guided Imams through whom the Prophet's authority continued. Its Twelver, Ismaili, and Zaidi branches divided over the succession within that line.
Source: The Nahj al-Balagha, attributed to Ali ibn Abi Talib.
Confidence: high
Sunni Islam
Sunni Islam is the tradition of roughly nine in ten of the world's Muslims. It carries no single head and no central magisterium; its unity stands in the shared scripture, the Prophet's example, the four schools of law, and the theological schools that defended them.
Source: The Qur'an; the Hadith collections of al-Bukhari and Muslim.
Confidence: high
2. Scale and spread
How large the entity is and where it is found: adherents, bodies, and geography, with sources.
Shia Islam
Shia Islam counts roughly 150 to 200 million adherents, about ten to thirteen percent of all Muslims. Shia form majorities in Iran, Iraq, Bahrain, and Azerbaijan, with large communities in Lebanon, Yemen, Pakistan, India, and Afghanistan.
The range inside, as documented:
- Sufism: The mystical path of Islam: remembrance of God, the master-disciple chain, and the orders that carry it, crossing the Sunni and Shia branches alike.
Source: Pew Research Center, 'Mapping the Global Muslim Population' (2009).
Confidence: high
Sunni Islam
Sunni Islam counts roughly 1.6 billion adherents, about 87 to 90 percent of all Muslims, and is the majority form of Islam in most Muslim-majority countries, from Indonesia and South Asia to North Africa and Turkey.
The range inside, as documented:
- Ash'ari Theology: The theological school of al-Ash'ari, which defends the Sunna with reason: the Qur'an uncreated, God's attributes affirmed without asking how, and human acts created by God and acquired by persons.
- Sufism: The mystical path of Islam: remembrance of God, the master-disciple chain, and the orders that carry it, crossing the Sunni and Shia branches alike.
- Maturidi Theology: The theological school of al-Maturidi of Samarkand, paired with Hanafi law, which gives reason a larger place in knowing good and evil than its Ash'ari sister school.
- Mu'tazila Theology: The rationalist school that held God's unity and justice as its two principles, read the Qur'an's anthropomorphisms allegorically, and held the Qur'an created; the school the Ash'ari synthesis answered.

| What this comparison cannot settle | populated: This comparison sets two self-descriptions side by side; it does not decide between them. A tradition is a living range of positions, and each panel renders the range this site has documented, which is not the whole of the tradition. Where a cell is marked not yet documented, the gap belongs to this site's documentation, not to the tradition. Questions of truth between the panels turn on premises the reader brings: what counts as evidence, what authority is recognized, and what a human life is for. The instrument does not score, rank, or adjudicate. | populated: This comparison sets two self-descriptions side by side; it does not decide between them.
